The documentary Supersize Me uses various camera techniques, lighting, editing, and archival materials to critique the fast food industry. It follows Morgan Spurlock as he eats only McDonald's for 30 days. Close-up shots show his declining health as well as interviews and statistics about fast food. The setting of hospitals and schools alongside props of cartoon mascots portray how fast food negatively impacts both children and adults. Sound design incorporates diegetic eating sounds and non-diegetic music to further critique fast food. Through Spurlock's experiment and analysis of fast food marketing techniques, the documentary argues that fast food consumption can seriously endanger health.
